Dashes in state name break state transition detection

[chris-ware]

There is an issue with

laravel-model-states/src/StateConfig.php

Line 89 in 4761952

[$transitionFromMorphClass, $transitionToMorphClass] = explode('-', $allowedTransition);

where if the morph class contains a - character, it can't find the class. This a fully understandable constraint, as the dash character is used in the code to determine transition states by key, however there may be a better way of handling this. I had thought that adding a constraint to the explode to only return 2 items would work, but that then breaks if both items have a dash in the name or if the dash is placed in the first state.

I think it may be more prudent to just thrown an exception somewhere that prevents dashes from being used, as trying to find the cause of this issue has taken well over an hour.
